The objective of this study is to describe the understanding that sheltered female adolescents have regarding motherhood and analyze their experience of this process from their perspective, for the purpose of identifying a support structure for young sheltered mothers. This exploratory and qualitative study was performed at two municipal shelters in Rio de Janeiro. The data were collected through focal groups performed with 10 sheltered adolescents. The content analysis of the data revealed two categories: Motherhood in adolescence: the perspective of the sheltered adolescent and Being a mother at the shelter: positive and negative experiences. Being a mother during adolescence is an ambivalent experience for the sheltered adolescents. The shelter is described as a supportive environment, but difficulties still exist in helping them to construct a healthy image of motherhood. There is a need to sensitize the social actors involved in terms of creating intersectoral interventions regarding the context and lifestyles of these youths, which could prevent vulnerability/disaffiliation of mother and child.
